compressive strength of a concrete masonry unit:

EVALUATING THE COMPRESSIVE STRENGTH OF

UNIT STRENGTH METHOD. The unit strength method is often considered the least expensive and most convenient of the three methods. However, the unit strength method also tends to yield more conservative masonry strengths when compared to the prism test method.. Compliance with f’ m by the unit strength method is based on the net area compressive strength of the units and the type of mortar
